It wasn't an answer to your question. I too would like to know why this VVEL thing needs to be 'cracked'. If I understand this VVEL stuff, it gives fuel economy while cruising and power when you step on it. Seems simple - intake valves open sooner i.e. longer duration with a higher lift and the timing is advanced accordingly for power when you get on the throttle . In cruise, for fuel economy, the timing is retarded, valve lift is reduced and begins later. Someone correct me if I'm wrong. Your tuner, as you stated, adjusted timing and fuel delivery to produce good gains in HP. Did he mention anything about cracking the VVEL 'secret'?
